NON-REFILLABLE BOTTLE.

SPECIFICATION forming part of Letters Patent No. 788,115, dated April 25, 1905.

Application filed November 10, 1904. Serial No. 232,093.

Be it known that l, FREDERICK A. MULLER, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented new and useful 1mprovements in Non-Refillable Bottles, of which the following is a specilication.

My invention relates to a device which is designed to prevent therelillingot bottlcsafter their contents have once been exhausted.

It consists in the combination and arrangement of parts which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a vertical section of a portion of a bottle, showing my invention applied. Fig. 2 is a detached perspective view of the plugs T. Fig. 3 is an enlarged detached view of the valve with its stem and weight. Fig. is a detached perspective view of a plug 9. Fig. 5 shows a split ring detached. Fig. 6 is a view similar to Fig. 1, showing the plugs and split ring in position. Figs. 7 and S are views similar to Fig. 6, but showing plugs of mod i lied to rm.

It is the object of my invention to prevent the relilling ot bottles which have once been emptied.

in carrying out my invention the bottleneck A is blown in such a manner as to form a contracted seat, as at 2, between the neck and the body 3 ot' the bottle. \Vithin this neck the ball-valve l is titted and adapted to close hermetically upon the seat at 2. In order to retain this ball in position and prevent l its being raised from the seat in any way except by absolutely inverting the bottle. .l have shown a weight, as at 5, connected with the ball-valve l by an intermediate rod or connection, as at 6. This weight depends into the body of the bottle, and it the bottle be turned upon either side it will swing to the lower side of the bottle and will act to retain 1 These devices working in umson term a very the the valve upon its seat. In order to prevent introduction ot a wire or tampering in any way with this ballvalve through the neck, I have shown various devices interposed between the mouth of the bottle-neck and the ballt. One of these devices consists of plugs,

as at 7, which are retained in the neck between the plug 9 and the ball a, and these plugs are formed with radial disks, channeled, as shown plainly in Fig. 2 at 7. There may be two or more of these disks connected rigidly by intermediate shanks of smaller diameter, as shown at 8, and the points 7 are so disposed that the points of one of the plugs will coincide with the inter-spaces of the adjacent plugs, thus providing a tortuous pasthrough which it would be impossible to introduce a wire or other implement. An additional protection is provided by means of a plug, as at 9, which is tixed in the neck of the bottle above the plug 7 in various ways. Thus plug 9 may have any suitable or tortuous passage made through it, as at 10, and it is locked into the neck of the bottle in any suitable or desired manner. Thus it may be introduced and lixed in place by means of a body of cement which lills an enlargement in the bottle-neck and also a reduced portion of the plug 9, which coincides with this enlargement, as shown at 11. Another method would be to make the plug in two parts, the lower part of the plug coinciding with the enlargement, and a piece of cork or other expansible or noncorrosive material 16 may be introduced into a chamber in the lower part of the plug, as shown at 12. This substance when expanded by being moistened or otherwise softened will separate the two parts of the plug at the bottom and will force the enlarged lower portion into the correspomling enlargement of the bottle-neck, and thus lock it in place, so that it cannot be removed.

In another form the central portion of the plug may be of a reduced diameter, and an elastic ring, as l-l, may be sprung into the groove and the plug then pressed inward until the ring will engage with a coincident annular groove in the bottle-neck, as at 15, which prevents removal of either plug or ring.

complete obstruction to the introduction of liquid from the outside; but by reason of the passages through and around the ditl'erent parts the contents may be readily discharged when the bottle is inverted.

Having thus described my invention, What 1 claim, and desire to secure by Letters Patent, is

1. A bottle having a seat at the junction of the neck and body, a valve closable upon the seat, a plug fixed above the valve composed of a plurality of separated disks, with openings Which do not register, and intermediate shanks of smaller diameter, and a second plug fixed above the first-named plug and having a tortuous passage therethrough.

2. A bottle having a seat at the junction of the neck and body, a valve closable upon the seat, a superposed plug composed of parallel FREDERICK -A. MULLER.
